Answer:
The form is y=mx+b where m is the slope and b is the y-intercept
1)
y=4/3x-5
2)
y=-3/2x+4
y-intercept is (0,4)
4-1/0-2=3/-2=-3/2
3)
y=-2/3x
y-intercept is (0,0)
0-(-2)/0-3=2/-3=-2/3
4)
y=2x-1
9-3/5-2=6/3=2
y-9=2(x-5)
y=2x-10+9
y=2x-1

Slope = 3
x-intercept = 28/3 = 9.33333<span>
y-intercept = 28/-1 = -28.00000

Answer:
sec A= 1.01 and cot B =8.25
Step-by-step explanation:
Given :
sec A and cotB if a =8 and b=7
Now,
=
and
Therefore, answer will be sec A= 1.01 and cot B =8.25
Answer:
b .
x = 3
y = 3
Step-by-step explanation:
Using the pythagorean identities for 30-60-90° triangle,
we know the ratio of the sides is x - x√3 - 2x
Since 2x = 6
Then smallest side is x (opposite ∠30°) = 6/2 = 3
The other side y , opposite ∠60° will be x√3 or 3√3.
Answer:
40
Step-by-step explanation:
Given problem:
x² - y²
x+ y = 10
x - y = 4
Solution:
Using the concept of differences of two squares;
x² - y² = (x + y)(x - y)
So;
x² - y² = 10 x 4 = 40
